| 摘 要： | 对甘蔗继代培养绿苗中的内源激素进行测定、分析,同时进行生根诱导。结果表明:甘蔗组培苗在继代过程中,IAA,CTK,GA1＋3有积累效应,其中IAA的积累较慢,CTK,GA1＋3积累在第9代后较快,同时第9代后生根率也明显下降,在第10代出现不能诱导生根的矮化丛生苗。绿苗中IAA,CTK,GA1＋3的含量与生根率相关性显著。

| Abstract: | Studies on the endogenous hormones and rooting induction in plantlet of sugarcane subculture were reported in this paper. It was showed that IAA, CTK and GA 1 3 of sugarcane plantlet had an accumulative effect in subculture, the IAA accumulated slower than CTK and GA 1 3 , moreover, the CTK and GA 1 3 accumulated quickly in the 9 th generation of subculture. But the rooting rate reduced in the 9 th generation of subculture. The shortened and clustered buds can't be induced to generate root in the 10 th subculture. The content of IAA, CTK and GA 1 3 in plantlet is significantly correlative with rooting rate. |
